Abstract
A system for monitoring the operation of a surface pump such as a hand-operated water pump or oil pump, which uses an accelerometer mounted to a component of the pump to monitor movement of a pump component, for example the handle, and transmitted via a data connection such as a mobile data communications network to a server. The accelerometer measurements are processed by using a trained model such as a support vector machine to output an indication of the condition of the pump or the level of liquid in the well or borehole served by the pump. The model may be trained using a training data set of sensor measurements associated with liquid level in the well and condition of the pump.
Claims20
A system for monitoring a surface pump for raising liquid from a well, the monitoring system comprising:
- a surface pump comprising a handle for operating the pump;
- a sensor mounted on or associated with the handle, wherein the sensor is configured to sense movement of the handle and provide an output signal representative thereof;
- and
- a signal processor for receiving the sensor output signal and processing it to derive therefrom an estimate of the level of liquid in the well or an estimate of the condition of the pump or both.
A method of monitoring a surface pump for raising liquid from a well, the method comprising:
- measuring movement of a handle of the pump and providing an output signal representative thereof;
- receiving the output signal and processing it to derive therefrom an estimate of the level of liquid in the well, or an estimate of the condition of the pump or both.
